24C04 256x8(2k) Serial CMOS EEPROM

Description

aP89021 high performance Voice OTP is fabricated with Standard CMOS process with embedded 512K bits EPROM. It can store up to 21sec voice message with 4-bit ADPCM compression at 6KHz sampling rate.8-bit PCM is also available as user selectable option.Two trigger modes,simple Key trigger mode and Parallel CPU trigger mode facilitate different user interface. User selectable triggering and output signal options provide maximum flexibility to various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving output minimize the number of external components. PC controlled programmer and developing software are available.

Features

16 PIN DIP
Standard CMOS process
Embedded 512KB EPROM
21 sec voice length at 6KHz sampling rate and 4-bit ADPCM compression
Maximim 12 vocie groups
Combination of voice building blocks to extend playback duration
960 table entries are available for voice block combinations
User selectable PCM or ADPCM data compress
Two trigger modes are available by whole chip option during voice compilation. Key Trigger Mode - combinations of S1 ~ S4 to trigger up to 12 voice groups, SBT for sequential trigger. CPU parallel trigger mode - combinatios of S1 ~ S4 with SBT goes HIGH to strobe start the voice playback
Voice group trigger options : Edge / Level : Hold / Unhold : Retrigger / Non-Retrigger
Whole Chip Options : Ramp / No Ramp. Output Options : Key Trigger Mode / CPU trigger mode
16ms ( @ 8KHz sampling rate ) debounce time for both key and cpu trigger modes
RST pin set to HIGH to stop playback at once
Three User programmable outputs for STOP pulse, BUSY signal and flashing LED
Built - in oscillator to control sampling frequency with an external resistor
2.2V ~ 3.6V single power supply and <5uA low stand-by current
PWM Vout1 and Vout2 drive speaker directly
D/A COUT to drive speaker through and external amplifier
